You should split the titan into pieces.
Arm, legs, Head, body, etc.
To break pieces off, make the model an 'editable poly', go into the polygon selection, select the polygons and use 'detach', then check the 'detach to element' box.
Then split those in half, rotate the back half and then move any vertices that happen to behind anything.
Then arrange the pieces, place a 'uvw mapping' modifier on it, Planar. Make sure it covers all the pieces.
Then put a 'uvw unwrap' modifier on it, and click edit, then using that move any pieces that are the same so that they overlap each other.
Once that is done, use textporter to make a texture file.
It may be the long, and slightly difficult way to do it, but it will give you the best results in skinning.
Remember that when you have the skin you want, go into the 'uvw unwrap' modifier and click save, and save the .uvw file.
Later on the model, the unbroken up one, give it a 'uvw unwrap' modifier and load the .uvw file you loaded earlier so that the skin wraps the model properly. |
